## Long description

The BlueOptics QSFP-40G-D-AOC-20M QSFP 40GBASE-SR4 20m Blue is an active optical cable engineered for 40G Ethernet and Infiniband FDR10 links. With a 20-metre active assembly and QSFP connectors at both ends, this cable supports short-reach multimode transmission at 40 Gbit/s, delivering low latency and stable signal quality for high-density networking environments such as data centres and server farms.
Advantages
This active optical cable integrates transceiver electronics into the cable assembly to provide low power consumption and reduced signal loss over the 20 m link. Compliance with the 40GBASE-SR4 physical layer ensures interoperability with compatible QSFP ports and switches. The pre-terminated QSFP connectors simplify installation, reduce the need for field splicing or transceiver modules, and help maintain predictable performance in structured cabling deployments.
Suitable for
40G Ethernet links between switches, routers and aggregation devices
High-performance computing and Infiniband FDR10 interconnects
Top-of-rack and spine connections in data centres
Server-to-switch cabling in high-density server racks
Key specifications
Data rate: 40 Gbit/s (aggregate)
Standard: 40GBASE-SR4 multimode optical specification
Connector type: QSFP on both ends (pre-terminated)
Length: 20 metres
Cable type: Active optical cable (AOC) for multimode operation
Latency: low, suitable for latency-sensitive applications
How to use
Install the cable by inserting each QSFP connector into the corresponding QSFP port on the devices, ensuring correct alignment and a secure seating. No separate transceivers or fibre termination are required. Follow device vendor guidance for port configuration and link testing; the link should be recognised automatically by systems that support 40G QSFP optics. Avoid tight bends and protect the cable from sharp edges or excessive pulling forces during routing through racks and conduits.
Usage recommendations
Use this 20 m BlueOptics QSFP AOC for short-reach links inside data centres where predictable 40G performance and simplified deployment are required. Verify compatibility with switch and router QSFP ports and follow manufacturer guidance for supported link modes and firmware requirements.
